Pectoral Sandpiper (Calidris melanotos) Science Article 1 abstract During the summer of 1992 we placed wire-mesh exclosures around 13 of 52 Pectoral Sandpiper (Calidris melanotos) nests near Oliktok Point on the North Slope of Alaska. Exclosures were 66-69 cm in diameter, 31-cm tall, and were made of 5 X 10-cm mesh weld-wire with 3-cm mesh […]
Effectiveness of predator exclosures for pectoral sandpiper nests in Alaska
Pectoral Sandpiper (Calidris melanotos) Science Article 1 abstract During the summer of 1992 we placed wire-mesh exclosures around 13 of 52 Pectoral Sandpiper (Calidris melanotos) nests near Oliktok Point on the North Slope of Alaska.

Phylogeny of the cuckoo genus Coccyzus(Aves: Cuculidae): a test of monophyly
Pearly-breasted Cuckoo (Coccyzus euleri) Science Article 1 abstract Coccyzus comprises nine species of New World cuckoos (Aves: Cuculidae)that breed from southern Canada to central South America. The phylogeny of thisgenus was reconstructed using 2490 base pairs of the mitochondrial genes cytochromeoxidase II and III, and cytochrome b. Maximum likelihood, maximum parsimony,and Bayesian inference approaches produced […]

Peach-fronted Parakeet feeding on winged termites
Peach-fronted Parakeet (Aratinga aurea) Science Article 1 abstract Insectivorous habits in parrots are reported for the Australasian genus Culyptorhynchus, which seem to feed habitually on larvae of wood-boring insects in addition to seeds and fruits (Forshaw 198 1). Among Neotropical psittacids insectivory is poorly known, although Forshaw (1981) believes that these birds are far more […]

HABITAT SPECIFIC BEHAVIOR OF THE PARAKEETAUKLET IN THE BARREN ISLANDS, ALASKA
Parakeet Auklet (aethia psittacula) Science Article 1 abstract We are not aware of any published accounts of the behavior of the Parakeet Auklet. Previous studies of this species have centered on its ecology in the Bering Sea (Bedard 1969a, 1969b, Sealy 1968, Sealy and Bedard 1973). Our intent is to discuss and relate the basic […]

Comparative foraging ecology of planktivorous auklets in relation to ocean physics and prey availability
Parakeet Auklet (aethia psittacula) Science Article 2 abstract tested the hypothesis that the spatial distributions of foraging least, crested and parakeet auklets (aethia pusilla, A. cristatella and A. psittacula, respectively) in the shallow passes of the Aleutian Islands would be determined by physical mechanisms that control near-surface prey concentrations. We recorded currents using an Acoustic […]
